I canmot really blame you or the website, until i investigate where the cause came from because:
1. It could be you allowing hackers in for not setting 2fa or the hacker hacked your phone to get your pwords and 2fa
2. It could be that the website was hacked.
In the second case, it won't be only one account, it is usually a pack of accounts with stolen funds.
In any case. STAY SAFE
Be careful, nothing is safe on the internet. This problem is complex, even though we provide multiple security, such as 2Fa, mobile phone, and email authorization, but if hackers are able to hack our device then it will all be in vain. Avoid phishing websites by marking original websites that we often visit with bookmarks or shortcuts. Avoid storing large amounts of assets in the wallet exchange. The rest, pray to avoid theft.
